Hi,
The pthread_attr_getstacksize() and pthread_attr_setstacksize()
functions, respectively, shall get
and set the thread _*creation*_ stacksize attribute in the attr
object.
What i need is current stack size of a running thread. My problem is
that i have a thread with constantly growing stack ( i can see it via
/proc/PID/smaps ). Thread uses some functions from a proprietary
shared library. I need to know when the stack size of the mentioned
thread reaches RLIMIT_STACK so i can safely restart that thread before
it crashes.

Muli, how do you get the pthread_attr_t object for the currect
thread?
If you don't mind only being portable to GNU systems:
pthread.h:
#ifdef __USE_GNU
/* Initialize thread attribute *ATTR with attributes corresponding to the
already running thread TH. It shall be called on unitialized ATTR
and destroyed with pthread_attr_destroy when no longer needed. */
extern int pthread_getattr_np (pthread_t __th, pthread_attr_t *__attr) __THROW;
#endif
Not sure what's the non-portable way of doing it.
Cheers,
Muli
